Emerson adds a new measurement analysis capability on Rosemount 848T temperature transmitters.Emerson Process Management’s new Measurement Validation Diagnostic is now available on the Rosemount 848T Foundation fieldbus temperature transmitter. This new capability detects temperature measurement and process abnormalities, which allows users to take preventative action to avoid unnecessary shutdowns, process inefficiencies, and safety issues.  

Temperature sensors, such as thermocouples and RTDs, can degrade over time due to harsh process conditions, vibration, and other factors. By evaluating the variation in the temperature measurement, the new utility can detect abnormalities related to degraded sensors, as well as electronic interference, corroded termination points, loose electrical connections, and process upsets. By alerting the user of these issues, degraded temperature sensors can be replaced before they fail, or other preventive action can be taken. Measurement validation also calculates the process rate of change which can help users detect runaway reactions before alarm conditions are met.
